C'LAMPING PIN Filed July 29, 1929 vwa w Patented Apr. 22, 1930 FIREDRICK G.'WAGE1\TER, OF CHICAGO, ILLINOIS cLA'MI'ING PIN Application filed July 29, 1929. Serial No. 381,882.

This invention relates to improvements in clamping pins and, more especially, such a pin adapted to be secured to fabric and can rying clamping means for securing thereto 5 another piece or end of material, for example,

fabric. I

The invention, for example, is Well adapt- I ed for use in connection with sanitary bandages. It is extremely simple and convenient 10 in use and a great improvement on the common safety pin.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawings Figurel is aview in perspective showing the device in use; Fig. 2 is a view taken as indicated by the line 2 of Fig. 1; Fig. 3 is a view in perspective showing the pin open; Fig. 4 is a View in perspective of a modified form; and Fig.5 is a view taken as indicated by the line 5 of Fig. 4.

As shown in'the drawings, 10 indicates an open rectangular frame having pivotally mounted on one end a pin 11 for securing the device itself to a fabric.

The pointed end 11 of the pin 11 is adapt- 0 ed to be secured in the clasp 12.

v Numeral 13 indicates a clamping bar also pivoted to one end of theframe 10. This clamping bar is channel-shaped in cross section and provided with teeth l3 along the edges. When the'pin 11 is secured in fabric,

the bar 13 may be swung into clamping position parallel to and straddling the pin 11 to clamp anotherpiece or end of material be tween the pin 11 and bar 13. The bar 13 may locking bar 14 pivoted to the other end ofthe frame, also channel-shaped in cross-section,

and adapted to be snappe'd'or sprung down over the bar 14, as shown in Fig. 2.

The modified formshown in Fig. 4 is the same as the other except that the locking bar be held inclamping position by a shorter snapped or sprung over the retaining knob 115 to hold the clamping bar in clamping position.

As an example of one use for the device, it. is shown in Figs. 1 and 2 as secured'or pinned to the tab 15 of a belt 16 and-the clamping bar 13 is shown clamped over the end17'of a' sanitary bandage.

'While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore in the construction and arrangement may be made without r departing from the spiritand scope of my invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible, in view of the prior art.

What I regard as new, and desireto secure by Letters Patent, is:

1. A device of the character described, ineluding; a frame; a securing'pin pivotally attached to the frame; a clasp carried by the frame for the end of the securing pin; a clamping bar carried by the frame and adapted to be swung into clamping position adjacent the securing pin to clamp material between the pin and bar; and means for holding the clamping bar in clamping position.

2. A device as claimed in claim 1, in which the clamping bar is channel-shaped in crosssection and adapted to straddle the pin when in clamping position.

3. A device as claimed in claim 1, in which the clamping bar is channel-shaped in crosssection and provided with teeth on its edges and adapted to straddle the pin when in clamping position. 7

4. A device as claimed in claim 1, in which the clamping bar is adapted to be held in clamping position by a channel-shaped locking bar pivoted to the frame and adapted I to be sprung over the clamping bar.

In witness whereof, I have hereunto set my hand, this 19th day of July, 1929.
